MATERIALES Y MÉTODOS:  Estudio de dos cohortes, prospectivo y retrospectivo efectuado con base en la información de expedientes clínicos de pacientes atendidas en el Complexo Hospitalario Universitario de Ourense entre 2017 y 2018. Se establecieron dos cohortes: la cohorte A con edad mayor o igual a 40 años y la cohorte B con edad menor de 40 años. Se realizaron pruebas paramétricas y no paramétricas para determinar la asociación potencial entre las variables de estudio (&#967;2, t de Student, U de Mann-Whitney).  RESULTADOS: Las pacientes de la cohorte A (n = 207) tuvieron significación estadística: índice de masa corporal mayor al inicio del embarazo (p = 0.028), mayor cantidad de embarazos previos (p = 0.001), a expensas de mayor cantidad de abortos (p &lt; 0.001), estados hipertensivos del embarazo (p = 0.03), prematurez (p = 0.009), retraso en el crecimiento intrauterino (p = 0.006), macrosomía fetal (p = 0.04), inducciones (p &lt; 0.001), cesáreas programadas o intraparto y hemorragia posparto (p = 0.001). No se encontraron diferencias en la paridad, amenorrea al parto, diabetes pregestacional-gestacional, peso fetal medio, Apgar, pH de la arteria umbilical y cantidad de recién nacidos con requerimiento de ingreso a la unidad de Neonatología.  CONCLUSIONES: La edad materna avanzada es un factor de riesgo importante de morbilidad materna y perinatal. La mayor tasa de complicaciones descritas refleja la importancia del control exhaustivo del embarazo y vigilancia periparto minuciosa.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[Abstract  OBJECTIVE: To describe the maternal and perinatal results in pregnant women with advanced age.  MATERIALS AND METHODS:  A cohort study was conducted with prospective follow-up and retrospective data collection of the Clinical History of the University Hospital Complex of Ourense between 2017 and 2018. Two cohorts were established, cohort A with age greater than and equal to 40 years and the cohort B with age under 40 years. Parametric and non-parametric tests were performed to determine the potential association between the study variables (Chi-Square, Student&amp;apos;s T, Mann-Whitney U).  RESULTS: The cohort A patients (n = 207) presented with statistical significance: body mass index higher at the beginning of pregnancy (p = 0.028), higher number of previous pregnancies (p = 0.001), but at the expense of a higher number of abortions (p &lt;0.001), hypertensive states of pregnancy (p = 0.03), prematurity (p = 0.009), intrauterine growth retardation (p = 0.006), fetal macrosomia (p = 0.04), inductions (p &lt; 0.001), of both scheduled and intrapartum caesarean sections and postpartum hemorrhage (p = 0.001). No differences were found in parity, amenorrhea at delivery, pregestational / gestational diabetes, mean fetal weight, Apgar score, umbilical artery pH and number of newborns who required admission to the Neonatal Unit.  CONCLUSIONS: Advanced maternal age is an important risk factor for maternal and perinatal morbidity. The higher rate of complications described reflects the importance of thorough pregnancy control and careful peripartum surveillance.]]></p></abstract>
